Filter HTML and CSS style tags __html

Now you want to take a part of the content of the article as a description on the page, as shown in the following illustration:

The data in the red box is part of the content of the article, but the content of the article will be stored in the format of HTML code, etc.

To display the normal need to filter the HTML tags, the code is as follows:

public string Delhtmltag (string htmlstr) { 
        string regex_style= ' <style[^>]*?>[\\s\\S]*?<\\/style> "; The regular expression 
        String regex_html= "<[^>]+>" that defines the style;//defines the regular expression pattern P_style=pattern.compile for HTML tags 
         
        ( regex_style,pattern.case_insensitive); 
        Matcher M_style=p_style.matcher (HTMLSTR); 
        Htmlstr=m_style.replaceall (""); Filter style label pattern 
         
        p_html=pattern.compile (regex_html,pattern.case_insensitive); 
        Matcher M_html=p_html.matcher (HTMLSTR); 
        Htmlstr=m_html.replaceall (""); Filter HTML tags 
        
        htmlstr=htmlstr.replace ("", "");
        Htmlstr=htmlstr.replaceall ("\\s*|\t|\r|\n", "");
        Htmlstr=htmlstr.replace ("" "," ");
        Htmlstr=htmlstr.replace ("" "," ");
        Htmlstr=htmlstr.replaceall ("", "");
          
        return Htmlstr.trim (); Returns a text string 
    

The program simply calls:

String content = delhtmltag (content);
